Title: Radio-pulse-echo device for measuring the distance of moving objects
IPC: G01S13/526
Filed: 1945-09-13
Abstract: 617,243. Radiolocation. SADIR-CARPENTIER. Sept. 13, 1945, No. 23642. Convention date, March 3, 1944. [Class 40 (vii)] In a recurrent-pulse system for measuring the range of moving objects, received echo signals are recorded at a relatively-slow rate and taken off from the recording medium at two spaced points, the two reproductions being applied in opposition to an indicator so that echoes from fixed objects are eliminated. The slow recording of the echo signals is effected by connecting the receiver to the recorder through a gate circuit opened only for the duration of a pulse, the point in the pulse-recurrence period at which the gate is opened being progressively moved so as to pass during a large number of periods the whole of the reflected signals. In the arrangement shown, at each transmission of a pulse from aerial 2, a pulse from transmitter 1 passes also through a variable delay network 5 to the gating circuit 9. The network 5 provides a maximum delay equal to the pulserecurrence period and comprises a number of similar sections connected to contacts engaged by a wiper 6 rotating at a speed related to the pulse recurrence frequency but much lower. Echoes of progressively-increasing range are thereby passed through the gating circuit 9. The echoes are fed to a recording device comprising a recording head 10, a travelling magnetic ribbon 11 and two spaced pick-up heads 12 and 13. The rate of travel of the ribbon 11 and the distance between the pick-up heads 12 and 13 are such that energy corresponding to echoes arriving at constant time intervals, i.e., echoes from fixed objects, is picked up simultaneously by the two pick-up heads. The energy picked up by the head 13 is reversed in polarity by a device 14 and fed to a circuit 15 in which it meets and cancels any energy picked up simultaneously by the head 13. Any energy passing through the circuit 15 corresponds to echoes which arrive at progressively changing time intervals, i.e. to echoes from moving objects and this energy is fed to the vertical deflection system of a cathode-ray tube 16, the time base of which is provided by a generator 19 synchronised with the movement of the wiper 6. Each moving object gives rise to two indications spaced apart and of opposite sign, the distance of the first from the origin representing range and the distance between the two indications giving a measure of the relative speed.

Abstract: 360,895. Duplicating sound records. HUGUENARD, E. A., 19, Rue Dupont de 1'Eure, Paris. Aug. 8, 1930, No. 23747. [Class 40 (ii).] Sound - record films, in which the groove is of the hill-and-dale type, are duplicated by passing together a blank film 2 and the master film 1 to be copied between an abutment 5 engaging in the record groove and a cutting.tool 6 engraving the blank film, the two films being in back-to-back contact at this point, so that the abutment causes the blank to be cut more or less deeply according to the variations in depth of the groove in the master film. The speeds of the two films may either be the same or unequal. The cutting tool may be heated, e.g. electrically, or may be assisted by the use of a solvent. A wider groove may be produced in the copy than in the original. Both the abutment 5 and the tool 6 may be fixed ; or either may be resiliently mounted and movable under inertia control, so as to modify the form of the groove cut in the copy. In a further arrangement, Fig. 2 (not shown), a light resilient strip, fixed at one end, is interposed between the two films, and the abutment 5 and the tool 6 may be placed out of alignment, so that the abutment may be either nearer to or farther from the fixed end of the strip than the cutting tool. With this arrangement, the groove in the copy may either be cut more deeply or may be made shallower than in the original. The invention may be applied to kinematograph films bearing a sound record groove in the " non- gelatine " side.

Filed: 1927-09-12
Abstract: 287,790. Ingersoll-Rand Co., (Assignees of Lear, E. B.). April 6, 1927, [Convention date]. Percussive drills.-In a percussive drill, the valve-chest is provided with bushings U, V, of which U seats in a recess Z and is held in position by a plate E which closes the valvechest end and the cylinder end, and the other bushing V is provided with a screwed stem W which projects through the front of the chest and receives a nut X. The fluid outlet v is arranged between the bushings. The valve is tubular to permit the passage of fluid, has an enlarged central head q which controls the exhaust port v and has opposed actuating- areas s, t upon which the exhaust from the cylinder acts to throw the valve, has reduced ends which enter recesses g in the bushings, and has collars which enter borings in the bushings and provide areas y, z upon which the fluid acts to hold the valve. The cylinder has crossed inlet passages x, w leading from the valve-chest ends, and exhaust ports u, v. When the piston in its forward-motion passes port u, the cylinder pressure acting on the annular s against the resistance of the locking-pressure on area Z reverses the valve and opens the outlet v to the left-hand end of the cylinder. Fluid then passes by passage x to the forward end of the cylinder A, and acting on area y holds the valve to the right until the piston opens the port v. The drill is provided with water and air tubes L, O respectively for conveying cleansing-liquid and pressure fluid from the back head H to the tool. A water plug R screwed into the head secures the tubes in position. Specification 288,534, [Class 122 (ii), Steam-engine distributing and expansion valves &c.], is referred to.

Abstract: A screen composition, especially for television tubes and other specified purposes, comprises a metallic orthogermanate activated by a metal which confers the property of luminescence on excitation by radiant energy.  To obtain greater brilliance during scanning elements may be added which yield X-rays under cathode ray bombardment, (e.g. 1 to 10 per cent of molybdenum, tungsten, thallium, tin, platinum, or compounds thereof).  To obtain a greater degree of secondary radiation a radio active substance may be added (e.g. \ba1/10,000\be per cent to 1 per cent of radium, mesothorium, actinium or compounds thereof).  The following preparation is specified.  A bimolecular weight of magnesium or zinc oxide is powdered with a unimolecular weight of germanium dioxide.  A solution of manganese chloride (e.g. containing \ba1/10,000\be per cent to 1 per cent of the combined weight of the above ingredients) is added, and the mixture fritted at a sufficient temperature (e.g. 1000 DEG C.) to make it semi-fluid.  The zinc composition gives a bright green-yellow under ultra-violet and cathode ray excitation.  The magnesium composition gives orange or scarlet-red.  Manganese dioxide may be used instead of a manganese halide.

Abstract: 479,537. Automatic circuit-breakers; actuation of switches. GENERAL ELECTRIC CO., Ltd., and KEELEY, F. J. Sept. 3, 1936, No. 24138. [Class 38 (v)] Electric - switch operating- gear comprises one member adapted to be driven, a second member adapted to drive, a latch or equivalent device for connecting together the two members, tripping means adapted upon operation to render the device inoperative, and means adapted in the event of disconnection of the two members while force is being transmitted from the second to the first member and as the result of relative movement between the two members to prevent rapid movement or acceleration of the second member in the direction in which it moves during transmission of this force. The operating lever 7 is adapted to be coupled to the operating shaft 17 by means of a latchlever trippable by means of a trip coil, the arrangement being such that the latch-lever can be tripped at any part of the closing movement, Lever 7 is fastened to a lever 6 and carries a trunnion 5 in which is fastened a hollow piston-rod 4 carrying a ported piston 8 in an oil-filled cylinder 1. Passing through the rod 4 and trunnion 5 is a stem 13 carrying a valve 9 in the cylinder 1, the arrangement being such that when nuts 14 on stem 13 are in contact with the trunnion 5, the valve 9 is spaced away from the piston 8. To close the switch, lever 7 is first raised and with it lever 6, the valve 9 remaining in open position. In this movement a spring or springs 20 are tensioned by levers 16 fastened to lever 7, and the latch connection between 7, 17 is made. Lever 7 is then pressed downwardly and, aided .by springs 20, rotates 17 to close the switch. In this movement, a finger 18 on shaft 17 maintains valve 9 open by engaging the end of stem 13. If, however, the switch is tripped during closing, arm 6 at once accelerates with respect to finger 18 and valve 9 is closed to retard or stop the lever 7. The actual tripping arrangement is shown in Fig. 2. Energization of coil 24 rotates lever 25 clockwise, which in turn acts on a lever 26 pivoted at 27 and provided with a roller at 28 engaging the curved part 29 of a lever 30 over' its whole travel. Lever 30 is pivoted to lever 7 at 31 and is adapted to move a further lever 32, which deflects the lever 21 locking the lever 7 to the arm 22 on shaft 17. In Fig. 3 (not shown), a spring for assisting closure is fitted in the oilcylinder between the lid thereof and the top of the piston, and ports are provided in the valve instead of in the piston.
